Abstract
Description
Technical Field
[0001] This utility model relates to the field of central air conditioning technology, specifically to a central air conditioning duct with self-cleaning function. Background Technology
[0002] Central air conditioning systems are widely used in large buildings such as office buildings, shopping malls, and hospitals. After long-term operation, their piping systems are prone to accumulating dust, dirt, and broken leaves, leading to a series of problems. For example, dirt on the inner walls of the pipes increases airflow resistance, reduces heat exchange efficiency, and increases energy consumption. In addition, moisture and dirt provide a breeding ground for bacteria, mold, and other microorganisms, polluting the air and harming human health.
[0003] Currently, the most common methods for cleaning central air conditioning system pipes are installing filters and machine cleaning. For example, filters are installed to trap dust, but this method requires regular filter replacement and cannot remove dirt already attached to the pipe walls. Machine cleaning involves using mechanical devices such as brushes and high-pressure water guns to clean the pipes, but this method is complex and difficult to clean bends and narrow sections. Utility Model Content
[0004] The main technical problem to be solved by this utility model is to provide a central air conditioning duct with self-cleaning function. The device has a simple structure and can realize the self-cleaning of the central air conditioning duct without disassembling the central air conditioning duct. It can complete the cleaning without frequent maintenance and replacement, and can improve the cleaning efficiency of the central air conditioning duct.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] A self-cleaning central air conditioning duct includes an air conditioning pipe. One end of the air conditioning pipe is equipped with a drive motor. The output end of the drive motor extends into the interior of the air conditioning pipe and is connected to a cleaning component. The cleaning component includes a rotating shaft with several spiral blades on it. Each spiral blade has an air groove, and the edge of the spiral blade abuts against the inner wall of the air conditioning pipe.
[0007] The following are further optimizations of the above technical solution by this utility model:
[0008] One end of the rotating shaft is connected to the output end of the drive motor.
[0009] Further optimization: The wind grooves on the spiral blades are arranged at intervals along the direction of the spiral blades, and the area of each wind groove on the spiral blades accounts for 70%-80% of the area of the spiral blades.
[0010] This design ensures the airflow effect of the central air conditioning system during use, allowing the cold or hot air output by the central air conditioning system to circulate through the air ducts in the air conditioning pipeline.
[0011] Further optimization: The edges of the spiral blades are made of rubber.
[0012] This design makes it easy for the spiral blades to collect dust, leaves, and other debris.
[0013] Further optimization: A cleaning box is detachably connected to the outer wall of the air conditioning pipe, and the cleaning box is connected to the inside of the air conditioning pipe.
[0014] This utility model adopts the above-mentioned technical solution, with ingenious design and reasonable structure. The spiral blades, under the action of centrifugal force, collect dust, leaves and other debris in the air conditioning pipes, and then discharge the debris through the cleaning box. This can achieve self-cleaning of the central air conditioning pipes without disassembling them. It can also prevent the growth of microorganisms on the inner wall of the pipes, improve safety and hygiene performance, and extend the service life of the air conditioning pipes. In addition, the design of the air ducts does not affect the flow rate of cold and hot air in the air conditioning pipes, which helps to reduce energy consumption.
[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0019] like Figure 1-2 As shown: A self-cleaning device for central air conditioning pipes includes an air conditioning pipe 1. One end of the air conditioning pipe 1 is provided with a drive motor 3. The output end of the drive motor 3 extends into the interior of the air conditioning pipe 1 and is connected to a cleaning component 2. The cleaning component 2 includes a rotating shaft 21. The rotating shaft 21 is provided with spiral blades 22. Each spiral blade 22 has several air slots 23. The edge of the spiral blade 22 is in contact with the inner wall of the air conditioning pipe 1.
[0020] One end of the rotating shaft 21 is connected to the output end of the drive motor 3 for transmission. This design allows the cleaning component 2 to operate through the drive motor 3.
[0021] The wind grooves 23 on the spiral blade 22 are arranged at intervals along the direction of the spiral blade 22, and the area of the wind groove 23 on each spiral blade 22 accounts for 70-80% of the area of the spiral blade 22.
[0022] This design ensures the airflow effect of the central air conditioning system during use, allowing the cold or hot air output by the central air conditioning system to pass through the air duct 23 in the air conditioning pipe 1, thus preventing the cleaning component 2 from reducing the output airflow speed of the central air conditioning system.
[0023] The edges of the spiral blades 22 are made of rubber, which makes it easier for the spiral blades 22 to collect dust, leaves and other debris.
[0024] A cleaning box 11 is detachably connected to the outer wall of the air conditioning pipe 1, and the cleaning box 11 is connected to the interior of the air conditioning pipe 1.
[0025] With this design, the cleaning box 11 is used to collect dust, leaves and other debris from the air conditioning pipe 1. When the cleaning box 11 is full of debris, it can be replaced directly, making it convenient to use.
[0026] In this embodiment, the cleaning box 11 is placed below the air conditioning pipe 1 during installation, so that the cleaning box 11 can collect debris inside the air conditioning pipe 1.
[0027] When in use, first turn on the drive motor 3, which drives the rotating shaft 21 to rotate. When the rotating shaft 21 rotates, it will drive the spiral blades 22 to rotate and generate centrifugal force. Through the contact between the spiral blades 22 and the inner wall of the air conditioning pipe 1, the dust, leaves and other debris deposited in the air conditioning pipe 1 are collected and transported until they are delivered to the cleaning box 11. The debris in the air conditioning pipe 1 is discharged by replacing the cleaning box 11, which plays a cleaning role.
[0028] When the cleaning component 2 is stationary, the cold and hot air in the air conditioning duct 1 can pass through the air duct 23 without the cleaning component 2 reducing the airflow speed of the air conditioning duct 1.
[0029] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
